SANTEC Unveils Ultra High-Power TSL-570 Type U Tunable Laser to Address Optical Loss Challenges in AI-Driven CPO Architectures
Product Name: Ultra High-Power Tunable Laser
Model: TSL-570 Type U
Santec LIS Corporation (Komaki, Aichi, Japan; hereinafter “Santec LIS”) announces the launch of its latest product, the TSL-570 Type U, an Ultra High-Power Tunable Laser designed to deliver significantly enhanced optical output for Co-Packaged Optics (CPO) and advanced silicon photonics applications.
The markets for CPO and silicon photonics are expected to see strong growth, driven primarily by the rapid expansion of AI-driven data centers and high-performance computing architectures. CPO systems inherently require optical signal splitting across multiple waveguides, resulting in substantial splitting, coupling, and waveguide losses. These challenges are driving increased demand for high-power, wavelength-tunable laser sources capable of supporting accurate and repeatable device characterization.
By optimizing the laser cavity design and control circuitry, Santec LIS has achieved more than three times the optical output of previous TSL-570 models. With this capability, the TSL-570 Type U serves as an ideal laser source for CPO and silicon photonics evaluation, supporting a broad range of use cases from research and development to volume manufacturing test environments.
Key Features:
- Ultra high-power optical output for high-loss photonic architectures
In continuous-wave (CW) operation, delivers optical output power exceeding +25 dBm (300 mW) across the 1300 to 1320 nm wavelength range.
- Wide wavelength tuning range with sustained high output power
Consistently delivers more than +20 dBm of optical output while covering a broad wavelength range from 1270 to 1350 nm.
Start of Order Acceptance: February 1, 2026
